There can be a plenty of way to do this one thing i can suggest you to create a class name something DataBean which will contain all the records which you will want to display to user.So your DataBean Class Could be something like this

public class DataBean{
String name;
String parentID;
//Getter,Setter of above varaible
}

Now when you are creating your model give this DataBean class to the model something like this

List<DataBean> dataList = new ArrayList<>();

here you can see dataList would contain all the record of type DataBean class so you do not need to write any complex logic into the ZUL file.

Rather than you can write logic in Java Class to set the values in DataBean class.

The following example works and uses the function getClientName.

<zk> <style> .red { color: red; } </style> <zscript>

    class A
    {
        public A(String s, Long v, Boolean is_group)                    { s_= s; v_= v; is_group_= is_group; }

        public String getLabel()        { return s_; }
        public Boolean isGroup()        { return is_group_; }
        public Long getValue()          { return v_; }

        public String getClientName(Long v)     { return s_+ " -- "+ v.toString(); }

        String s_= null;
        Long v_= null;
        Boolean is_group_= null;
    }

    lm.add(new A("Today", 1L, Boolean.TRUE));
    lm.add(new A("RE: Bandbox Autocomplete Problem", 2L, Boolean.FALSE));
    lm.add(new A("RE: It's not possible to navigate a listbox' ite", 3L, Boolean.FALSE));
    lm.add(new A("RE: FileUpload", 4L, Boolean.FALSE));

    lm.add(new A("Yesterday", 10L, Boolean.TRUE));
    lm.add(new A("RE: Opening more than one new browser window", 11L, Boolean.FALSE));
    lm.add(new A("RE: SelectedItemConverter Question' ite", 12L, Boolean.FALSE));

    lm.add(new A("Last week", 100L, Boolean.TRUE));
    lm.add(new A("RE: Times_Series Chart help", 101L, Boolean.FALSE));
    lm.add(new A("RE: SelectedItemConverter Question", 102L, Boolean.FALSE));

    class VM
    {
        public ListModel getListModel()     { return lm; } 
    }
